Parameters

  • patterns:

    The patterns to detect on the pasteboard.

  • itemSet:

    An index set with each integer value identifying a pasteboard item positionally in the pasteboard. Pass in nil to request all pasteboard items.

  • completionHandler:

    A block that the system invokes after detecting patterns on the pasteboard. The block receives a Result instance that contains either an array of dictionaries with the patterns and the associated values found on the pasteboard or an error if detection failed.
